Structure and function

Structure

Automatic sensor

recognition

The sensor electronics with the stored sensor data is in the connecting head. 
The data include, among other things, the sensor type and series number. 
With each calibration, the calibration data is written in the sensor and the 
calibration history is recorded. The data is recalled by the meter when the 
sensor is connected and is used for measurement and for measured value 
documentation. Storing the calibration data in the sensor ensures that the 
correct cell constant is automatically used if the sensor is operated with 
several meters.

The digital transmission technique guarantees the failure-free 
communication with the meter even with long connection cables. If the sensor 
firmware is enhanced by WTW, it can be updated via the meter.
